Bear in mind, this is all self-reported data from the 2012 and 2014 cycles. There are some unusual occupations listed: "sovereign nation" (which gave heavily to Republicans), "bridge professional" and "openly gay congressman," as Rep. Jared Polis (D-Colo.) listed himself in a 2012 contribution. There are endless variations on particular titles -- CEO, C.E.O., C. E. O., etc. -- and endless combinations of jobs. (For example, there are 45 different "actor-slash" combinations in the system: actor/teacher, actor/mother, actor/homemaker.)
We made a tool that allows you to search for any occupational description that was used in at least 50 contributions over the last two cycles and to see which party benefited from that job's generosity. This isn't percentages in terms of actual dollar amounts; instead, it's the number of donations. And an important note! This uses the description given to the FEC and that alone. So people whose occupation was "not-employed" gave more to Democrats, but those calling themselves "unemployed" gave slightly more to Republicans.
